THE PIKE PERCHES. 13 
The largest and most important form is St#zostedion vitreum, generally 
referred to by recent writers upon fishes as the Wall-eyed Pike. This 
well-known species is’ found in nearly all the water systems frequented 
by S. canadense, and in many others, its geographical range being much 
more extended. It inhabits the Great Lakes and their confluents,* and oc- 
curs in most of the little lakes of Western New York,—Cayuga, Seneca, 
Chatauqua, Oneida and many others. It ranges north to the fur countries, 
and is doubtless widely distributed through British America. It is found 
in the Susquehanna and the Juniata, in the Ohio River, and many of its 
tributaries, in Western Virginia and North Carolina, in Kentucky, in Rock 
Castle River and elsewhere in Tennessee, especially in the French Broad 
and at least as far south as Memphis, in Georgia in the Oostanaula river 
and, it is said, in Arkansas. Its range to the south and southwest deserves 
careful investigation. 
THE WALL-EYE. 8. VITREUM. 
Jordan recognizes two subspecies of Stizostedion vitreum—the typical form 
S. vitreum vitreum, and asmaller, heavier bodied form which is bluer in color 
and is generally known as the Blue Pike, S. v¢reum salmoneum. This, he 
states, is a local variety in Ohio and southward. It has been considered a 
distinct species by many naturalists since the days of Rafinesque. 
The geographical range as well as the classification of the American 
Pike-Perches, as the reader must have inferred from what has been said 
about them in these pages, need to be studied much more exhaustively before 
a satisfactory essay can be written upon them. Their habits are very im- 
perfectly understood, and it will be necessary to refer to what is known of 
their kindred in Europe, in order to give even a partial idea of their life- 
history. 
In the Old World, as in the New, there are two well marked species, 
_ *A specimen was taken in April, 1887, in the Connecticut river at Portland, as recorded by Professor Wil- 
liam North Rice.
